Booking Sequence Diagram

Sequence diagram system of airline reservation system.-You can edit this template and create your own diagram. Creately diagrams can be exported and added to Word, PPT (powerpoint), Excel, Visio or any other document. Use PDF export for high quality prints and SVG export for large sharp images or embed your diagrams anywhere with the Creately.
Sequence diagrams are organized according to time. The time progresses as you go down the page. The objects involved in the operation are listed from left to right according to when they take part in the message sequence. Below is a sequence diagram for making a hotel reservation.

Booking System Sequence Diagram The diagrams show an example of objects interaction in time sequence in a booking system. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to.

Notation Description	Visual Representation
Actor a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data) external to the subject (i.e., in the sense that an instance of an actor is not a part of the instance of its corresponding subject). represent roles played by human users, external hardware, or other subjects. Note that: An actor does not necessarily represent a specific physical entity but merely a particular role of some entity A person may play the role of several different actors and, conversely, a given actor may be played by multiple different person.
Lifeline A lifeline represents an individual participant in the Interaction.
Activations A thin rectangle on a lifeline) represents the period during which an element is performing an operation. The top and the bottom of the of the rectangle are aligned with the initiation and the completion time respectively
Call Message A message defines a particular communication between Lifelines of an Interaction. Call message is a kind of message that represents an invocation of operation of target lifeline.
Return Message A message defines a particular communication between Lifelines of an Interaction. Return message is a kind of message that represents the pass of information back to the caller of a corresponded former message.
Self Message A message defines a particular communication between Lifelines of an Interaction. Self message is a kind of message that represents the invocation of message of the same lifeline.
Recursive Message A message defines a particular communication between Lifelines of an Interaction. Recursive message is a kind of message that represents the invocation of message of the same lifeline. It's target points to an activation on top of the activation where the message was invoked from.
Create Message A message defines a particular communication between Lifelines of an Interaction. Create message is a kind of message that represents the instantiation of (target) lifeline.
Destroy Message A message defines a particular communication between Lifelines of an Interaction. Destroy message is a kind of message that represents the request of destroying the lifecycle of target lifeline.
Duration Message A message defines a particular communication between Lifelines of an Interaction. Duration message shows the distance between two time instants for a message invocation.
Note A note (comment) gives the ability to attach various remarks to elements. A comment carries no semantic force, but may contain information that is useful to a modeler.

Actor

a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data)
external to the subject (i.e., in the sense that an instance of an actor is not a part of the instance of its corresponding subject).
represent roles played by human users, external hardware, or other subjects.

Note that:

An actor does not necessarily represent a specific physical entity but merely a particular role of some entity
A person may play the role of several different actors and, conversely, a given actor may be played by multiple different person.

Lifeline

A lifeline represents an individual participant in the Interaction.

Activations

A thin rectangle on a lifeline) represents the period during which an element is performing an operation.
The top and the bottom of the of the rectangle are aligned with the initiation and the completion time respectively

Call Message

A message defines a particular communication between Lifelines of an Interaction.
Call message is a kind of message that represents an invocation of operation of target lifeline.

Return Message

A message defines a particular communication between Lifelines of an Interaction.
Return message is a kind of message that represents the pass of information back to the caller of a corresponded former message.

Self Message

A message defines a particular communication between Lifelines of an Interaction.
Self message is a kind of message that represents the invocation of message of the same lifeline.

Recursive Message

A message defines a particular communication between Lifelines of an Interaction.
Recursive message is a kind of message that represents the invocation of message of the same lifeline. It's target points to an activation on top of the activation where the message was invoked from.

Create Message

A message defines a particular communication between Lifelines of an Interaction.
Create message is a kind of message that represents the instantiation of (target) lifeline.

Destroy Message

A message defines a particular communication between Lifelines of an Interaction.
Destroy message is a kind of message that represents the request of destroying the lifecycle of target lifeline.

Duration Message

A message defines a particular communication between Lifelines of an Interaction.
Duration message shows the distance between two time instants for a message invocation.

Note

A note (comment) gives the ability to attach various remarks to elements. A comment carries no semantic force, but may contain information that is useful to a modeler.
